Use a nice editor like SciTe, select your code, press Ctrl + Q and done. On Eric4 there is an easy way: select a block, type Ctrl+M to comment the whole block or Ctrl+alt+M to uncomment. This and powerful regex search/replace is the reason I tolerate Emacs's other 'eccentricities'.ġ3.5k 11 gold badges 58 silver badges 74 bronze badges Un-comment the code: highlight, then C-x-r-k Highlight the code you want to comment out, then C-x-r-t # You can use ''' foo ''' for docstrings and ''' bar ''' for comments or vice-versa to make the code more readable.Ģ,911 4 gold badges 23 silver badges 23 bronzeĪnother editor-based solution: text 'rectangles' in Emacs. Vi or Emacs you can create a macro to do this for you for a block of code. Many Python IDEs can add # for you on each selected line, and remove them when un-commenting too. Note that the code will still need to have proper syntax. The only way you can do this without triple quotes is to add an: if False:Īnd then indent all your code. That won't be mistaken for a docstring, eg: '''ĥ19k 102 gold badges 646 silver badges 825 bronze badges The only cure I know for this is a good editor. Temporarily, this is fine as a temporary measure.

Most Python IDEs support a mechanism to do the block-commenting-with-hash-signs automatically for you. Prepend a # to each line to block comment.
